Abstract
The spectral analysis of free vibrations of bridge span beams is one of the significant engineering problems aimed at ensuring the accuracy in determining the spectrum of natural amplitude-frequency characteristics and vibration shape for their compliance with real conditions.
Purpose: Identification of errors in impact forces and changes in acceleration as random variables and the errors analysis in recorded accelerograms of vibrations, depending on the type of inertial pulses.
Practical implications: An in-depth analysis of transformation of input disturbing pulses from impact using the Hertz method and output reactions in the form of complex spectra of the beam free vibrations.
